Description

This data set is a polygon coverage created in ARC/INFO that represents the generalized thickness of the Madison Limestone and Englewood Formation, Black Hills, South Dakota. The thickness of the Madison Limestone and Englewood Formation was determined by substracting the elevation of the top of the Deadwood Formation from the elevation of the top of the Madison Limestone. The elevations for the tops of the formations were determined from geologic logs for wells drilled as of 1998. The thickness coverage contains polygons that have single integer values representing a range of thickness.
